To prevent possible SERIOUS INJURY or DEATH from a

falling garage door:

• If possible, use emergency release handle to

disengage trolley ONLY when garage door is

CLOSED. Weak or broken springs or unbalanced

door could result in an open door falling rapidly and/

or unexpectedly.

• NEVER use emergency release handle unless garage

doorway is clear of persons and obstructions.

• NEVER use handle to pull door open or closed. If

rope knot becomes untied, you could fall.

INSTALLATION STEP 9

Attach the Emergency Release Rope

and Handle

• Thread one end of the rope through the hole in the top

of the red handle so “NOTICE” reads right side up as

shown. Secure with an overhand knot at least

1" (2.5 cm) from the end of the rope to prevent

slipping.

• Thread the other end of the rope through the hole in the

release arm of the outer trolley.

• Adjust rope length so the handle is 6 feet (1.8 m) above

the ﬂ oor. Ensure that the rope and handle clear the tops

of all vehicles to avoid entanglement. Secure with an

overhand knot.

NOTE: If it is necessary to cut the rope, heat seal the cut

end with a match or lighter to prevent unraveling.

INSTALLATION STEP 10

Electrical Requirements

To avoid installation difﬁ culties, do not run the opener

at this time.

To reduce the risk of electric shock, your garage door

opener has a grounding type plug with a third grounding

pin. This plug will only ﬁ t into a grounding type outlet.

If the plug doesn’t ﬁ t into the outlet you have, contact a

qualiﬁ ed electrician to install the proper outlet.

If permanent wiring is required by your local code, refer

to the following procedure.

To make a permanent connection through the 7/8" (2 cm)

hole in the top of the motor unit:

• Remove the motor unit cover screws and set the cover

aside.

• Remove the attached 3-prong cord.

• Connect the black (line) wire to the screw on the brass

terminal; the white (neutral) wire to the screw on

the silver terminal; and the ground wire to the green

ground screw. The opener must be grounded.

• Reinstall the cover.

To avoid installation difﬁ culties, do not run the opener

at this time.

To prevent possible SERIOUS INJURY or DEATH from

electrocution or ﬁ re:

• Disconnect ALL electric and battery power BEFORE

performing ANY service or maintenance.

• Garage door installation and wiring MUST be in

compliance with ALL local electrical and building

codes.

• NEVER use an extension cord, 2-wire adapter, or

change plug in ANY way to make it ﬁ t outlet. Be

sure the opener is grounded.
